Korean Fair Trade Commission raids Google’s Seoul office

SEOUL—The Korean Fair Trade Commission raided the Seoul office of Google Inc. in connection with allegations of unfair trade in South Korea’s mobile-search-engine market, a person with direct knowledge of the matter said, the latest in a series of probes into Google’s operations globally.

Tuesday’s raid was part of an investigation by the antitrust regulator into accusations by Korean portal operators NHN Corp. and Daum Communications Corp. that Google is limiting their access to smartphones using the Android operating system.
